| Sep-23-02 | | numlock31: Thanks Sneaky. I noticed that you play on FICS. I used to play there but I went to gamecolony.com. I found the site to be more user friendly as well as having better graphics. You can have more info about your openents when you play them. (ie max rating; games won and lost etc) Its free to sign up and you can play for money as well. (If thats your thing.) There are no tutorials, however, which is a feature that I recall FICS having via the chessbot. |

| Oct-04-02 | | drukenknight: why isnt the fork Ne2+ good enuf, either on move 40 or maybe 39? Also why doesn't he promote 40 d1+Q+ so that he can come back and hit the bishop? |

 | | Sneaky: druken, the check just gives the king time to get away from the checks, e.g.
40 ...Ne2+ 41. Kh2 dxc1=Q? 42. Rxh6# Promoting on d1 is a much more interesting question. Clearly, 40...d1=Q+ 41. Rxd1 cxd1=Q+ 42. Kh2 Qxd4 and Black has the better game. I asked my computer what to do in this line and here's its opinion: 40...d1=Q+ 41.Kh2! Qxc1 (Qxd4 Rxc2 +-) and now a very pretty mate ensues: 42. Bxg7+! Rxg7 43. Rc8+ Kh7 44. Qf5+ Rg6 45. Rc7+ Kh8 46. Qf8+ Rg8 47. Qf6+ Rg7 48. Qxg7# |
|
| Oct-04-02 | | drukenknight: on the first line: 40...Ne2+ 41 Kh2 Nxc4! right? what does computer say? I don't have a computer chess program but maybe Im better off that way. I'll have to look at your computer line above more closely. Tonight I was looking at Korchnoi/Robatsch, I hope to find it in the data base and post my kibitz, I trust youve been looking at the Fisher/Browne game in the meantime? So maybe Ive found two saving moves for Karpov, tonight? hey wait a minute, what about 19...Rxe4? in the above game; and what about on the 22nd move, doesn't Karpov just allow a passed pawn? couldnt he have made wholesale trades on f2 and then covered his a pawn w/ Qa8? |
|
| Oct-04-02 | | drukenknight: on 40... d1=Q+ 41. Kh2! Kh7!?
welcome to the world of computer chess. In real life, Karpov probably only had a few minutes before the time control... |
|
| Oct-04-02 | | pawntificator: 36...Ne4 perhaps would have helped? |

| | Sneaky: <on the first line: 40...Ne2+ 41 Kh2 Nxc4! right? what does computer say?> First of all, it says that Nxc4 is the right move there--but it still loses: ...Nxc4 42. Rxc2 (d1=Q leads to mate in 7 with Rxh6+, just like we discussed below) Nxc6 43. Rxd2 +- <on 40... d1=Q+ 41. Kh2! Kh7!?> 42. Qg6+ Kh8 43. Qxh6# |
|
| Mar-08-05 | | Hesam7: Karpov blunders in a winning position. instead of 34...h6?? 34...♕e8!! would have won. |
|
| Sep-05-05 | | Brown: It wins? Personally, I really enjoy the sack exchange for two passed pawns by Karpov on move 19. Really an interesting position, beyond my powers to analyze, but exactly how 34...Qe8 wins is not clear. What happens after 35.Rxc2? Whoops, forget that, as after 35...Nxe2+ 36.Rxe2 Rc1+ wins, I think. |
|
| Sep-05-05 | | Kangaroo: How about <34 ... Qe8 35. Re3> ? |
|
| Sep-05-05 | | dac1990: <Kangaroo> 34 ...Qe8 35.Re3 Na2 36.Rxe5 Qxe5 37.Qd7 Rc5 38.Bxc5 Nxc1 39.Ba3 Ne2+  , according to Fritz 8.However 34 ...Ne2+! 35.Kf1 Bf4  and Black is dominating. It's a shame Karpov missed it. |
|
| Sep-08-05 | | Brown: <dac1990 34...Ne2+ 35.Kf1 Bf4> 36.Kxe2 Qc4+ and white has two responses. 37.Ke1 Re8+ 38.Be3 and what next? 38...d4?! loses to Rxf4 I think. After the knight is taken by white, the f4 Bishop is pinned on the f-file. Sure I'm missing something. Haven't looked at 37.Rd3 yet, but I think Ke1 looks winning for white. |
|
| Sep-10-05 | | Brown: Looking again, after 37.Rd3 Bxc1 looks strong for black. The bishop can move because with Rd3, there is no longer mate in two with Qf7+ The critical line I can see, sans computer is...
34...Ne2+ 35.Kf1 Bf4 36.Kxe2 Qc4+ 37.Ke1 Qb4+ 38.Kf1 Qd2 39.g3 <only move> Qxc1+ 40.Kg2 Qd2 <stopping Bd4> 41.Be3!? Qxe3 42.fxe3 c1=Q 43.exf4 Qc2+ 44.Rf2 <44.Qf2 Qe4 threatening Rc2 next looks winning.> Qe4+ 45.Kh2 d4 looks excellent for black. Any feedback is much appreciated. |

 | | tpstar: <Brown> Nice analysis - looks clean. You might consider adding mini-lines along the way for key branches, like 39. Rxf4? Qd1+! mates, and 41. Rxf4!? Qxf4! 42. gxf4 c1=Q wins, then 41 ... Qxe3! should get a "!" for show. Good job. I'm astounded that Black had such a powerful line combining offense and defense plus Queening threats. Yet moves like 34 ... Ne2+ & 35 ... Bf4 are not intuitive by any means, especially in time pressure. Great game by both players. |
|
| Sep-12-05 | | Brown: Thanks <tpstar>, really appreciate it. I'll take your advice and add more sidelines, but since I'm newer at this than others, I feel that maybe I shouldn't put any exclams or question marks too much, for my sense of what each is may be off. An interference move like 41,Bxe3!? is not an intuitive move, so it got some notes. Thanks again. |

| Nov-11-05 | | Hesam7: <all> I may have mixed 34... Ne2+ 35. Kf1 Qe8 with the immediate 34... Qe8. [It was 7 years ago!] But both of them win [this shows how good Karpov's position is at that moment] Here are analysis done by Fruit: [1] After 34... Ne2+:
35. Kf1 Qe8 36. Kxe2 Bb8 37. Kf1 Bxa7 38. Bxa7 Qb5 39. Kg1 Qxa5 40. Be3 Qb5 41. Rg3 Qe2 42. Bh6 Qd1 43. Kh2 Rc7 44. Bf4 Rf7 45. Rf3 (eval: -4.47) Depth: 17

| Nov-05-06 | | who: Incidentally, Yasser recommends 33...d4 but this actually loses to 34.Rf5! |

| Sep-17-08 | | Woody Wood Pusher: After 19..Rxf3 white seems to regroup very rapidly and the a pawn rolls quickly. Is this move still theory I wonder? After move 33 black has a very strong, maybe winning position but 34..h6? seems to throw it all away. Better is 34..Ne2+ 35. Kh1,Qe8! - +
(35..Nxc1? 36. Qf7+ mate in 3)
24..H6? 25. Qf7+, Kh8 
36..Na2 seems to put up a tougher resistance 37. Rxc2, Qxc2 38. Rxe5, Nc3 39. Re7 but 36..d4? + - loses quickly as in the game. Karpov must have been in severe time trouble at this stage. If he had gone 2-0 up in a 6-game match Anand would have been finished even sooner! |

 | | plang: Karpov's choice of the Moeller defense must have been a surprise to Anand as he had never played it before and it is not in character with his style. One of Karpov's seconds, Onischuk, uses the variation and he may have influenced the choice. Anand had played 8..Bg4 himself in a win against Kovacevic a few months before at Belgrade. 14 Qe2 was new, 14 Re1 had been played previously. Anand's sharp 18 d4 provoked Karpov's exchange sacrifice 19..Rxf3!. Anand felt he could have maintained a small advantage declining the cacrifice with 20 dxc..Rc3 21 Qxa6 but after the game continuation Karpov obtained more than enough compensation. 28..Ra8? would have been answered by 29 Qxa8+!..Qxa8
30 Bxe5. Anand got into trouble after 31 Bb6?; either 31 Rc1 or 31 a6 would have beeb better. 36 Re3 was apparently the move that Karpov had missed in his calculations. It eliminated the threat of ..Ne2 and threatened Rxc2 (ie if 36..Na2 then 37 Rxc2). |
|
| May-13-09 | | WhiteRook48: cannot prevent 43 Qxg7# |
|
| Apr-22-13 | | Everett: Wow, Karpov with the sweet exchange sac, <34..Ne2> would have ended things. |
|
| Sep-10-13 | | PinnedPiece: GTM Score 75 par 46.
I made a couple stupid moves--should have been somewhat higher. |
|
| May-05-18 | | Everett: I would have love to have seen <34..Ne2 35.Kf1 Qe8 36.Kxe2 Bb8+! 37.Kf1 Qb5+ 38.Kg1 Bxa7> The two backward baseline moves to win the game would have been epic Karpov. A missed brilliancy. |
